Karl Wright commented on LUCENE-6759:
-------------------------------------
So I tried to reproduce this in geo3d-land exclusively, and coded this:
{code}
c = new
GeoCircle(PlanetModel.WGS84,0.006204988457123483,0.003379977917811208,7.780831828380698E-4);
p1 = new
GeoPoint(PlanetModel.WGS84,0.005231514023315527,0.0034278119211296914);
assertTrue(!c.isWithin(p1));
xyzb = new XYZBounds();
c.getBounds(xyzb);
area = GeoAreaFactory.makeGeoArea(PlanetModel.WGS84,
xyzb.getMinimumX(), xyzb.getMaximumX(), xyzb.getMinimumY(),
xyzb.getMaximumY(), xyzb.getMinimumZ(), xyzb.getMaximumZ());
// Doesn't have to be true, but is...
assertTrue(!area.isWithin(p1));
{code}
The exact point in question shows up as outside of *even* the bounds computed
for the circle. So honestly I don't know how it wound up getting included?
Unless, perhaps, the descent decisions were made based on the approximation?
Looking at the code to see how to delve deeper...
